Catasetinae encountering problems while getting out of dormancy

[proteanorchid]

We've had a month of summer (max temps mostly ~>25C/ 77F) and some of my new catasetinae are taking their time to get out of dormancy.

Unfortunately some red spider mites got from one of my growing catasetums to the new growth of my Monn. Millenium Magic 'Witchcraft'. I've treated it with some alcohol swabs and an insecticide, but not before they inflicted some damage. I don't think the roots are as long as recommended before watering, but the growth does not look very healthy - its yellowing and there was quite a bit of leaf damage. So I was thinking of starting to water it to help it along...
Is this a good idea or should I let the it go without water for long hoping the old pseudobulbs (4 of them) will keep it going?


I also have a Clowesetum Penang Waltz that is small, whose new growth is starting to yellow and I think that needs some water because its old pseudobulbs are quite small. And lastly, this one's medium has shows quite a few salts that have mineralized on the medium, should I remove these or are the roots tough enough to handle it?

Added some photos.
The others are mostly either happily getting out of dormancy or in various stages of being out of sync with with my seasons :P But that's probably for a different post if people want to see that.
